I thought the SAP telnet port was only available via the local NIC on the server?

@TheCleaner - websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/sno/ui_entry/… says 'For 7.1 Netweaver systems and above, the telnet service is now more secure as it can only be accessed from the local host.'. Most of our systems are version 7.02 and I can telnet to these from my PC, but I cannot telnet to our systems running 7.1.
